Jackson could probably use the Wizards, The Barrow Wights, and even more so Shelob, to make the case. The Wizards, essetiall Angels taking shape as men, or manlike. The Barrowights, corpses re-animated by disembodied demons (Gothmog is that you? lol). Shelob, "an evil thing in spider form." The suggestion being that she is no true giant spider at all, but, like her mother, an evil spirit that has taken physical shape as a monster spider. With these as precedencts, an evil spirit in form like an orc is not so far-fetched. If the afore mentioned Gandalf vs. Bolg confrontation is going to be portrayed in a serious, challenging, one on one manner, I would rather it be Bolg the half-demon, or something of the sort, than Bolg the orc captain.

I must be missing that in the material the Peter Jackson is allowed to use... HoME is off limits to be used for his films. We are discussing the films and the material they can use for said films here. In the material PJ is allowed to use I see no mention of Zombie Orcs/Goblins or supernatural orcs anywhere. Personaly I don't care what Peter Jackson wants to include, its about what he can include, the Tolkien estate can sue him for using material outside the Hobbit and LOTR. You really think he's gonna take that chance? I'll buy that theory of Zombie orcs or supernatural orcs if you can point it out in the text that Jackson is allowed to use, the Hobbit and LOTR. Just find me one sentence where it refers to Azog or Bolg as being anything other than ordinary run of the mill large powerful goblins/orcs. Heck just find me a sentence about Bolg being "the torturer of Dol Guldur". Otherwise I think the idea is bogus and nothing at all in the "spirit of Tolkien"
